I break from the herd here, Dinner badassity is measured in deliciousness, not cost per serving.
That said, OP's dinner sounds great, and the cheap price is some tasty seasoning indeed.
I made beef wellington at the weekend. It was the best thing I have ever cooked.
but the price associated with it wasn't good. The following day I cooked a Turkey breast that I got via a raincheck at the local store. Still very good but very cheap and spread for another couple of meals.
If Badassity applied to cost then Beef Wellington is terrible. If it only applies to quality then Beef wellington is awesome.
Stretching my dollar on food so that I can occasionally cook beef wellington seems pretty badass to me.
Of course the best way to be a badass it to avoid eating out - there very little benefit gained. Cook at home - you can match the quality, control what foods you are eating and save money at the same time. Then you can spend the money saved on alcohol!!!
